.Application filed December 27, 1919. Serial l1\l'o. 3.7,61624.

To all lwhom t may concern Be Vit known that Hnunnnr JoNEs7 a citizen of Vthe United States, residing at B evier, in the'county of Macon and State of Missourij'have invented.' new and useful improvements in Marking Devices for.

'row `v mechanism',with means whereby the dista-nce between the "check-s can bead- Yju'sted tol suit the conditions.

lVith the above and' other objectslin view 'I will now proceed to describev a specific embodiment oftheinvention as illustrated in the 'accompanying drawings wherein:

Figure 1 is a side elevation of a planter having the invention attached thereto.

Figure 2 is an end elevation of the planter.

Figure 3 is an enlarged detail view of the spade.

Figure l is a top plan view of the planter with the invention in place.

Figure 5 is a detail sectional view throughy a supporting yoke embodied in the .invention.

Figure 6 is an enlarged detail view of the marking mechanism showing it in side elevation and in operative position.

In detail: Y y The corn planter to which this invention is applied may be of any suitable type A and for the purpose of illustration I have selected that type inwhich a seed check rod or rock shaft 1 extends across the trame F and serves to control the flow of grain from the grain receptacles indicated by the letters- A. As illustrated in Figure 1, one end of the rock shaft 1 is provided with a squared portion 2 whichis received within a squared socket member 3 vformed atone end Yor' a rearwardly extending rod 6. The squared socket member 3 is held on the squared portion 2 of the `rock shaft by means of a locking pin 4.

With reference to- Figures 2 and 5, it wil be noted that the rodG which extends rearwardly yfrom the rock shaft l1 is passeld l through a yoke 5 rigidly secured to -one side of the frame F by means of a bracket 25.

'The rod 6 is enlarged intermediate its ends and is slotted as indicated at`8 soY as'to re A ceive a vertically arrangedb'olt 9 extended through the yoke. During the operationfof4 the planter, the rod 6 partakes ot an up:- wardand downwardswinging movement,

and a contractile'coil spring 10 attached to the rod and to the bolt serves to 'normally` hold'the rod in its upward or elevated porsition. When the rear enlarged end portion 7 of' thev rod 6 isr moved downwardly' by means to -be `later described,4 the coil` spring 10 yields and serves to returnv the rod to its elevated position immediately upon being released. Y y

` The meansl` employed .for; periodically swinging the arm downwardly, comprises an y-'shaped memberr 13 extending laterally'Av `itrorn one Yof the` main` wheels'y SOYand secured theretobyan annulus 11 held upon' the spokes of the wheel by U-bolt's 12. .The intermediate portion of the member 13 exconstitutes a earn` for striking the enlarged portion 7 of the rod and moving the same downwardly whereby the seed dispensing mechanism will be operated.

V- As illustrated in Figures 1, 3 andA 6,`the vertical portion of lthe L-shaped vmember 13 is formed of a pair of hingedly connected sections 13'r1 and 13b the latter of which is provided with a spade or marking element sokr ' tends horizontally, as indicated at 21, and n 35 adapted to engage the ground as the Vwheel'is rotated. These sections 13a`and 13b are connected by a rule joint incliidin a gBy 95 pivot 14 and abutting shoulders 15. this construction it will be seen that the outer section 13b is adapted to be swung inwardly in a clockwise direction so as tobe outer sections in theopposite direction is 0f course prevented by theengagement of the shoulders 15.

In order to hold the outer sections 135 l in` alignment with the inner section so that the device will be operative, I provide a pair of laterally .extending apertured ears 18 on the inner section 13a valigning with a similar ear 18ak o-n the outer'section 13". Slidable through the ears 18 is a rod 13 which carries a collar 16El engaged by one end of a coil spring 17 which abutsagainst the innermost ear 18, the purpose of this spring being to force the rod 16 outwardly so that its outer end will enga-ge within the aperture of the ear 18a. The inner end or' the rod 16 is 'formed with an eye 16b within which is connected one end of a cord 1? or other ilexible member which is secured f to one of the spokes of the wheel and which it is merely necessary that the operator pull' upon the flexible member 17 and retract the rod 16 out of engagement with the ear 18a so that the outer section 13b may be swung inwardly and engage with the retaining members 22. I claim:

y 1. In a corn planter including a wheel supported frame, marking mechanism comprising an annulus secured upon one of the wheels, a bracket carried by the annulus and including hingedly connected sections, and a Aspring-pressed plunger connected with said sections Yfor holding the same normally in alignment, the spring-pressed plunger being withdrawable whereby to permit folding of the outermost section with respect to the other. Y

2. ln a corn planter including a wheel supported frame, marking mechanism comprising a member secured upon one of the wheels and including inner and outer sections connected by a rule oint, the rule joint permitting folding of the outer section on the inner section in one direction and preventing such folding in the other direction,

means for holding the outer section normally against movement in any direction comprising an apertured arm carried by the outer section, a pair of spacedapertured ears carried by the inner section land align*n ing with the lirst -named ear, an outwardly spring-pressed plunger slidable through the second named ears and normally engaging through the rst named ear, a flexible member connected with the inner end of the plunger whereby the same may be retracted to disengage the first named ear and spring retaining means on the inner section engageable by the outer section for holding the latter when in inwardlyswung position.

In testimony whereof I affix Iny signature.

HERBERT JONES.
